To all whom 'it 11mg/ cow/m:

Be it known that l., hllacin Fisn, a; citizen of the United States residingl at Strat-- ford, county of Fairiielfl. State oi' onneetieut, have invented an linprovei'x'xent in Voir.

able meters of this charaijr'lier Willi convenient means for making a temporary eonnee-- tion with the poles or binding serons oi a battery or magneto.

'With these and otherl in view .l

have devised the novel structure of which the following description in connection with the accompanying drawing; a specification., reference characters being need to indicate the several parts.

Figure l is an elevation showing Velt or arnmeter permanently provided Wit-ii my novel connecting means; Fig. E an edge view partly in sect-ion on the line .f-2 in Fig. l; Fig. 3 a View corresponding with Fig. l and illustrating a variant form of the invention; and Fi 4 is an elevation illustrating a form of the invention which 'is Wholly independent of the meter and .is adapted for use in connection with diiferent My present inventionenables me to de away with separate Wires and special Connections and to make an instant and eiffeetual connection between the poles ef a battery or magneto and the poles of a me ter, a single movement only being necessary te make or break the connection and the iin plement being always ready' for Lise.

The invention Consists in a pair of ter 40 minalsA indicated byfl() which are carried by arms 11, one or both of which 'are movable. The terminals are so shaped as to adapt them to make instant and convenient cenneetion with the poles of a battery or inagnetol and are insulated from the arm7 as at 1Q.- Eaeh of the terminals has cennected thereto a shorteoil of Wire, indicated by lis, the other 'end of which is connected or adapted to be connected with the poles of thenieter, In the forms illustrate-d in Figs.

l, 2 and 3, the arms and terminals are permanently Connected with and form :i parli' of the meter. In the form illustrated in Figs. l and' 2, the arms are provided with At the intersection of the arms and the handles the l niemlmrs are previded with overlapping eng largemenls i6 'which are shown as recessed into each other an(L are pivoted. as at l?, to the ease ci a meter. which is indiezll'efl by 1S. As the special i'orm of meter is wholly I inmaterial so :liar as the present iiivention is eoneerned, no description et the meter is timiight te be required and it will simply be i censidered whole. It will be noted that l the members, that is the arms and handles, de net cross each other at their point of intersection so that their operation the reverse oil that of a pair et shears. When the i iinger bows are pressed toward ear/ll other the terminals are meved apart and may ne Y.

.earlily placedv engagementwith the isles ci .ry or inagneto'and retained in ena bz gag'enient While the voltage er amperage is beig indicated by the meter.

The form illustrated in Fig. diilers only in that one the arms, indieated specifiaily by i9, and one of the handles indicated specifically by 20, are rigidly secured te the ease oi' the meter instead oi? being pivoted thereto as in the other forni, the other member, comprising an arm and handle, being pivoted to the ease before.

VThe ferm. illustrated 'in Fig. el is not attached to a meter ease, but is previ-:led with ed to be used with volt and ammeters as ordinarily placed upon the market. The members in this form are made as in Figs. l and 2 and are pivoted centrally te a clip indin cated as a Whole by 21. This clip comprises plurality ci armsatliree in the present instance, 'which are provided at their ends with lips f5 which are adapted to spring over the edge of a meter case5 -as elearl in? dieated in Fig. il, and. retain the meter inere- 'in while in use. The operation is preeisely the same asin the first form. The meter may yremain in the eli or may teremoved therefrom as preferre, l

Having thus described my invention .l claim:
